When I POST to the following, it is converting the non-zero JobNumber to 0 instead of the sent value.
[HttpPost("{testName}")]
public async Task<ActionResult<FirstPieceStamps>> PostFirstPieceStamps(string testName, [FromForm] FirstPieceStamps firstPieceStamps)
Here is the FirstPieceStamps model
public class FirstPieceStamps
{
[Column(TypeName = "decimal(10,3)")]
public decimal JobNumber { get; set; }
[Key]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int StampID { get; set; }
[Required]
public int TestID { get; set; }
[Required]
public int UserTypeID { get; set; }
[Required]
public bool Stamped { get; set; } = false;
#nullable enable
public string? FirstName { get; set; }
public string? LastName { get; set; }
#nullable disable
public FirstPieceJobs FirstPieceJobs { get; set; }
public FirstPieceTests FirstPieceTests { get; set; }
public FirstPieceUserTypes FirstPieceUserType { get; set; }
}
The request I'm trying to make from Postman to test it.
https://localhost:5001/api/FirstPieceStamps/Layflat?JobNumber=266019.001&Stamped=true&FirstName=John&LastName=Doe
The JobNumber value should be converted to a decimal number, but is instead being converted to just 0.
Check your use of FromForm. If you are really sending this POST as you have above, then the params are on the query string and you should be using [FromQuery] instead. I created a fresh Core 3.1 API project with your model and this controller method and it only worked correctly when I changed FromForm to FromQuery. If you want FromForm to work, then you need to remove them from the query string and use "form-data" option in Postman. With FromQuery, the full JobNumber with decimals came through.
